HUBERT H. HULL, OF CLEVELAND, OHIO, ASSIGNOR TO SHERWIN, WILLIAMS & CO., OF SAME PLACE.

IM PROVEM ENT IN CANS.

Specification forming part of Letters Patent No. 222,995, dated December 30, 1879 application filed October 30, 1879.

To all whom it may concern:

Be it known that I, HUBERT H. HULL, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Cans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to metallic cans, and more especially to that class constructed of tin-plate and used for permanent packages for the transportation of different articles, as paint, fruit, berries, dto.; and it consists in a rest or stop attached to the inside of the rim ofthe cover, whereby the latter is prevented, i

before soldering, from covering the can to the full depth of the rim.

In the drawings, Figure l is a vertical sectional view of a can and cover embodying my invention. Figs. 2, 3, and 4are sectional views, showing in detail the process employed in making this can-cover. Fig'. 5 is a plan view of the interior of a completed cover.

In the said drawings, A represents vthe body ofthe can, provided near its top with the usual bead a. This bead tends to throw the upper edge of the can inward, thus bearing upon and near the end of the lug or stop.

Bis the cover, which is made as follows: A piece of metal is cut of the desired size and shape. It is now taken in its dat condition, and the liange b, as shown in Fig. 2, is turned upon its edge. When dies are used the cover assumes the shape shown in Fig. 2, at the first operation. The tlan ge b is then iattened against the top of the can, as shown in Fig. 3. At this point(or before the flange b is flattened) the stops b2, as shown in Fig. 5, are provided, either by cutting a small piece from the flange b itself, and bending it out at right angles with the balance of the flange, as shown in Fig. 3, or by afxing a drop of solder to the flange at suitable intervals that would answer the purpose of a stop. The last operation in making the cover is performed by bending the double rim of the plate, as shown in Fig. 3, upon the dotted line .r y, and forming a new rim or iiange for the cover, consisting of a double thickness of metal.

The object of my inventionis to providea can that, having been filled with any commodity and the cover soldered thereon, may be readily opened without cutting or destroying the can.

Ve will suppose a can made in accordance with my invention to be tilled with paint, and the cover placed thereon; the stops b2 will not permit t-he can to enter the cover farther than the stops. The lower edge of the rim of the cover is now soldered tothe body of the can. The package is now complete and ready for shipment or use.

To open the can, the edges of the cover B are struck a sufficient number of blows to break the solder that unites the rim of the cover to the body of the can. This isreadily performed, as the top ofthe can does not bear against the under side of the cover, but against the stops b2. As the solder yields to the blows applied to the top of the can the stops bend back to place and peimit the solder to be readily broken, when the cover can be at once removed by simply lifting it from the can.

I/Vhat I claim is- The rim of a can-covir provided with temporary stops, whereby the upper edge of the can is temporarily prevented from contact with the cover, substantially as and for the purpose shown.

In testimony whereof' I have signed my name to this specification in the presence of two subscribing witnesses.

HUBERT H. HULL.
